SEATTLE -- Matt Hasselbeck's knee injury needs more tests.
The Seahawks' three-time Pro Bowl quarterback was inactive for Sunday's 27-17 loss to Green Bay, after being listed as questionable. That forced Seattle to use No. 3 quarterback Charlie Frye for his first start in two seasons, because backup Seneca Wallace is also hurting with a calf injury.
After Frye completed 12 of 23 throws for just 83 yards with two touchdowns, two interceptions and three sacks, coach Mike Holmgren said his team (1-4) will evaluate Hasselbeck's knee on Monday.
Hasselbeck said last week he has a bone bruise from getting hit early in the loss at the New York Giants on Oct. 5. He returned to play deep into the third quarter.
The Seahawks have been calling it a hyperextended knee, and Holmgren has said there is no structural damage -- at least none revealed in an MRI taken early last week.
"There is some more tests that he needs to take, apparently. It's hard to put a finger on it," Holmgren said.
He then turned his attention, without being asked, to getting Wallace back for this weekend's game at Tampa Bay (4-2).
"I think Seneca will improve day-to-day. So I would suspect he would be available to play next week," Holmgren said.
Hasselbeck was the lowest-rated passer in the NFC entering Sunday, after having six receivers hurt in the season's first month.
Both he and Holmgren thought he'd be fine to start on Sunday, but he did not practice all week while walking stiffly and wearing a leg wrap. And Holmgren said on Friday he did not want to put Hasselbeck in further jeopardy by playing if he was not fully ready.
So he missed his first game since Nov. 19, 2006, standing on the sideline in a white team pullover and neon green cap. He occasionally joined Frye for sideline discussions.
Seattle is 1-4 for the first time since 2002, its last losing season, and tied with St. Louis at the bottom of the NFC West.
"We're not used to being in the situation we are in. It's been a long time, but here we are. So how do we deal with it, as players and coaches?" Holmgren asked. "It's easy to slap people on the back and coach and play when things are going well. It becomes a little more difficult when it is not going so well."
